摘要

教師透過測驗來了解學生的學習情況，並針對學生學習較差的部分進行補強。因此教師將課程依章節或概念的方式提供給學生作測驗以掌握學生的學習情況；由於課程本身包含許多概念，學生在做概念檢測時都需要花費相當多的時間才能完成，而如何縮短學生測驗的時間，又能有效地掌握學生的學習狀態是本論文研究的重點。
學者將測驗題目搭配信心指標(confidence indicator)，讓學生在回答問題時可以針對自己的答案評估信心程度，藉由這種評估的方式鼓勵學生再次進行反思(reflection)；另外學生在測驗時答錯了題目，但是卻選擇了高度信心，這將會使得學生特別注意答錯的題目，而再次的思考尋求正確解答，根據標記信心等級達到更好的測驗效果。學者提出精熟度的測驗來檢測學生，透過連續機率比(SPRT)的檢定方式讓學生測驗時間縮短並且能夠有效地評估學生的學習狀態。
不論是利用信心指標來讓學生達到反思，抑或是使用精熟度縮短測驗時間，皆無研究針對上述兩項特點同時兼顧到。因此本研究設計一套信心指標搭配連續機率比(SPRT+)的檢定方式，並且在檢定完成後提供補救學習。評估此檢定方式能否使用較少的測驗題目數量完成檢定以及信心指標能否促進學生回答問題時做自我評估。

Teachers understanded students' learning state by tests, and focused on the part of learning fails doing remedial learning for students. Therefore, teachers will provide students with the chapter or concept test to control students' learning state in the courses; Because the course contains many concepts, students do the concept test needs to spend amount of time to complete, how to shorten the time of students’tests, and effectively controlled the learning state of students is the importance of the present paper.
Academics propose the test with confidence indicator, when students answer questions that can assess the level of confidence for their answers, and encourage students to reflection by the assessment; The other hand, the studentst got the wrong answer in the question, but chose the high confidence which will allow students to pay attention to the wrong answer of the question, and students thinking again to find the right answers. According to mark the level of confidence achieved better test effect. Academics propose the mastery tests to detect students, this way can reduce the time of tests and effectively assess students' learning state through continuous probability ratio test (SPRT).
No matter using confidence indicators to achieve the reflection for students or using the mastery test to shorten the test time are no research taking into account the characteristics of these two. Therefore, this study design a test integrating confidence indicators into continuous probability ratio test (SPRT+), and provide remedial learning after completed the test. Estimating this test will be able to use less number of test questions, and when answering questions confidence indicators can promote students to do self-assessment.
